NEOFIN BLUE

How good is Neofin Blue (high acutance) film developer with 35mm Efke 25?
Before I try it, would love to hear about other's experiences with this developer from J & C Photo.
Thanks for sharing your knowledge.

Joseph, I haven't tried the Neofin Blue, but have used PMK pyro with Efke 25. I have found it to be a good combination and would also like to hear about others with some experience using Efke 25 and NB. Curiously, both have metol as an active ingredient in part "A" so I'm sure there will be some similarities, at least with respect to agitation.

PMK works very well with Efke 25, but temperature and agitation both have a pronounced effect with respect to contrast and therefore need to be consistent from batch to batch. The grain is very fine with this developer, so I can tell you that it is a good film - developer combination to work with, especially with rollfilm and small size negatives. Hopefully, someone with some time using NB can tell you about it.

While stationed in Germany in the 70's I used Neofin Blue (Blau) with Agfapan 25, Panatomic-x, and Pan F with good results. I developed them in a metal tank and reels using intermittent agitation. It is a fairly old formula but very good. For higher speed films there was also Neofin Red (Rot).

Hans Beckert (alias Michael Scarspitty) has the dubious honor of being one of the few (maybe even the only one) that Sean banned from Apug. Not only because he fought a crusade against Rodinal, the Zone system and everything that wasn't Acutol. But because he fought a crusade against every PERSON that didn't agree with him. So you can just erase his remark about Acutol. His opinion doesn't mean anything useful.

I have been using NB with mostly Efke 25 for a while now with very reliable results. I process in a Jobo for 5.5 minutes @20c and I am able to enlarge to 11x14 with no grain troubles. This is a simply wonderful film!
